To all whom t may concern.

Be it known that we, WILLIAM L. KORN# .FELD and ARTHUR R. ENGLANDER,citizens of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Shade or Globe Su porting Means, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings.

This invention relates to a shade or globe supporting means for use withelectric lights, and has for its objects to provide mea-ns which may bereadily applied to a standard type of socket and firmly locked theretoso as to edectually support thel weight of a shade or globe; lto providea device of this character which is neat and attractive of appearanceand which con-l ceals a part of the socket and so harmonizes with theportion revealed as to produce a pleasing effect; to combine with a,shade holder of the foregoing nature an adapter which may be attached tothe holderin the same manner as a shade is attached thereto and which,in turn, incorporates globe sustaining means; and to constitute of saidadapter a reflector whereby the efiiciency of the light is increased.

The foregoing objects with others hereinafter appearin are attained inthe 'embodiment of the invention illustrated in the accompanying drawingwherein Fig. 1 is a sectional side elevation of a lighting fixtureequipped with the device of our invention showing it supporting a globein proper relation to anvelectric' amp; Fig. 2 is a side elevation, atright angles to Fig. 1, of the shade holder `ap lied to the lamp socket;and Fig. 3 is a plan view of what is shown in Fig. 2.

' An electric lamp of usual type is represented at 1 and the same issupported from a socket 2. The socket is of common form, comprisin ashell 1 that telescopes at its upper en 4 vwhich is suspended, t from awire concealing tube -6.

Our improved shade holder consists of a bell shaped casin 7 which is ofa diameter at its upper en to fit ,snugly about the upper end of theshell 1 and abut the lower ledge of the enlar ement 3. A bail 8 isconnected, by suita le pivot means 9,

into an enlargement 3 of a cap*` rough its boss 5,

notch 10 for the accommodation of said boss. The side branches ofthebail 8 are enlarged laterally to provide wings 11 that are formed tosnugly embrace the enlargement 3, the forward edges of the wings beingflared outwardly slightly, asindicated at 12 in F ig.V 3, to facilitatethe bails slipping over the enlargement. The casing 7 is notched at 13for the reception of the shank of a key 14; and atits lower edge isequipped with shade attaching means which are shown, in the presentinstance, as screws 15 that are threaded through the edge portion of thecasing.

It will be readily understood that a shade '(not shown) may be appliedto the holder by inserting the neck of the shade upwardly into the lowerend of the casing7 and projecting the screws 15 inwardly into engagementwith the neck, in accordance with common practice.

In the same manner an adapter 20 is attached to the holder. This ada teris shown as substantially frusto-conical in shape, terminating at its u`per end in a neck 21 and at its lower en in a vertical flange 22through which globe supporting means in the formv of screwsA 23 areextended, the flange beinlg shown as provided with bushings 24 t roughwhich the screws are threaded. This adapter is articularly suitable foruse with a specia form of globe which in the drawin is desi atedgeneralll by the numera 25. T e globe of itsel y It has a neck 26 at itsupper end that is adapted to be received within the lian e 22 and to beenga ed by the screws '23.' v to contour, the g obe 1s curved outwardly.and downwardly below'the neck 26 a suit-l able distance to a pointdesignated by the line A-A, and for a sui/table distance belowconstitutes no part of our invention.

thisl point to a point designated by line B-#B vsemi-spherical shape.Above the line A--A,

and below the line'B-B, the globe is trans'- lucent; while between saidlines it is transparent or clear. This results in a sort ofsemi-indirectl 1i hting effect, certain ra s from the lamp ing reflectedIdownwar y llO/r/ direction, of course, direct raysA escape through theclear ortion of the'` globe. While it is desirab e to soften the raysdescending from the lamp throu h the translucent lower portion of theglo e, too

much filtering of the light is extravagant and' objectionable and toincrease the eiiiciency of the light penetrating the lower portion "ofthe globe to a very considerable extent we finish the inner surface ofthe adapter 20, particularly the frustoconical portion thereof, to avery high brilliancy, as by silver plating and polishing in the mannerof finishing reflectors of usual type, so that the rays which wouldotherwise be lost are redeemed and cast downwardly, the majority of themfalling through the lower portion of the globe while some are cast olfthrough the transparent zonev between the lines A-A and vB--B. A

It is 'clearly' within the scope of our invention to alter the shape ofthat portion of the adapter 20 hereinbefore referred to as:truste-conical, itv being apparent that such portion maybe curvedaxially and, if desired, given the contour of a parabola.

Also', the adapter and shade holder may be constructed as a single unitwithout departingl from the spirit of our invention. Such modificationsas those sug ested are so obvious as to make specific illustration ofthem unnecessary. i

Having thus described our invention, what we claim is:

1. For use with a lamp socket having a circumferential enlargement, aglobe holder comprising a casing designed to fit over the lamp receivingend of the socket and concealed the same and have its inner end engagedwith said enlargment, and fa' bail hingedly connected to opposite sidesof the casing-and -adapted to be swung over the end of the socket remotefrom the lamp receiving end for positively holding the casing againstwithdrawal from the socket,

I the casing being 'provided with globe attaching mea s.

2. A shade holder for use with a lamp socket having a circumferentialenlargement, the holder comprising a casing adapted to be slipped overthe lamp receiving end of the socket with its inner ends in engagementwith the enlargment, while its opposite end is provided with shadeattaching 'means, and a bail pivotally connected to op osite sides ofthe casing and arranged to e swung over the end of the socket reyend inengagement with the enlargement,

while its opposite en'd is providedA with shade attaching means, and abail pivotally connected to opposite sides of the casing, the bailhaving a notch for the reception of the neck of the socket when the bailis swung into operative position, the opposite branches of the bailhaving parts frictionally engaging the enlargement of the socket to holdthe tion.

4. A shade holder for use with a lamp socket having a circumferentialenlargement intermediate its ends and terminating at its inner end in aneck, a casing adapted to be slipped over and' conceal the outer end ofthe socket and to have its inner end in engagement with the aforesaidenlargement, while its opposite end is provided with shade attachingmeans, and a bail ykpivotally connected at its ends to diametricallyopposed parts of the casing and hav'Y ing at its middle a neck embracingnotch adapted to receive the neck of the socket when the bail is inoperative position, the branches of the bail having laterally extendingwings which are formed to embrace the enlargement of the socket therebyto hold the bail in operative position.

5. A shade holder for use with a lamp socket having a circumferentialenlargement and provided at its inner end with a neck, a substantiallybell-shaped casing adapted to fit over and conceal the lamp receivlngend of the socket and arranged to have one of its ends ab t against theaforesaid enlargement, the o posite end of the shell incorporatinorshade attaching means, and a bail pivotally connected at its ends todiametrically opposed parts of the casing and having a notch whichembraces the neck of the socket when the bail is in 0perative position,the bail being formed so as to cooperate with the socket in such manneras to be held by frictional engagement therewith in operative position.

In testimony whereof, we hereunto afiiX our signatures.
